About This Simulation
Build your own battery to power an electric car! Discover the chemical reactions that power batteries by finding oxidation numbers, balancing redox reactions, and experimenting with redox reactions in the lab.
Learning Objectives
- Describe the concept of oxidation states and explain trends in the periodic table
- Apply the rules for determining the oxidation state
- Describe the role of the electron in reduction-oxidation
- Predict the direction of redox reactions
- Balance a redox reaction in both acidic and alkaline environments

Learn More About This Simulation
Oh no! Your electric car has broken down. Can you build your own battery to get moving again? Discover the chemical reactions that power batteries by finding oxidation numbers, balancing redox reactions, and experimenting with redox reactions in the lab, then make a recommendation to your friend Hansen about whether to replace his worn-out lead-acid battery with a new lithium-ion one.
Oxidation number and redox reactions
Join Dr. One in the redox chemistry lab to find out how redox reactions power batteries. Start by using the periodic table to predict the oxidation numbers of various compounds. Then balance the charges of half-reactions and see what happens to the oxidation numbers when electrons are lost or gained!
Redox potentials and balancing reactions
Develop and test a hypothesis about the reaction between copper and different aqueous solutions based on their reduction potentials. How can these potentials help you predict the direction of a redox reaction? Batteries can be both acidic and alkaline, so next up, join Dr. One to balance redox reactions one step at a time in both environments.
Optimize a galvanic cell
Now that you understand what a redox reaction is and what happens to the electrons, learn how this can be used to generate power in a galvanic cell. Experiment with different combinations of metal for the anode and cathode to find the most powerful duo. Will you be able to complete the reactivity series and discover another way of predicting the direction of redox reactions? Remember that you set out to find the best kind of battery to fix the electric car. With everything you now know about galvanic cells, what kind of battery do you recommend to your friend?

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."
